Answer:
C.
f(x) = 8*(x - 1)²
f(x) = 8x² - 16x + 8
Step-by-step explanation:
vertex form:
f(x) = a*(x - h)² + k
where (h, k) is the vertex of the parabola
In this case, the vertex of the parabola is at (1, 0). Replacing this information into the equation we get:
f(x) = a*(x - 1)²
The parabola passes through point (2, 8). Replacing this information into the previous equation we get:
8 = a*(2 - 1)²
8 = a
Then, the final equation is:
f(x) = 8*(x - 1)²
Expanding the quadratic term and applying distributive property:
f(x) = 8*(x² - 2x + 1)
f(x) = 8x² - 16x + 8
Answer:
36
Step-by-step explanation:
2(4.5*3)=13.5
2(3+7.5)=22.5
13.5+22.5=36
Answer:
11 meters
Step-by-step explanation:
w = 4
l = ?
2l + 4(2) = 30
2l = 22
l = 11 meters

#A
If we rool a die chances of even=chances for odd=3
#C
If we take names in equal amount probability remains same so we can do it
#D
By flipping a coin we have same probability for head and tail i.e 1/2.
For the options C, D, and E, (where the 3 sides are given) result in the construction of unique triangles.
<h3>Which conditions will result in the construction of a unique triangle?</h3>
We will have unique triangles only if the length of the 3 sides are completely determined, so we need to know the 3 sides, or two sides and one angle.
With that in mind, for options C, D, and E (in the 3 cases the 3 sides of the triangles are given). Then for these 3 options, we can make a unique triangle.
While for the first two options, where we only know the angles, we can make infinite triangles.
